Hydraulic Crawler Water Well Drilling Rig

Application
YSSL-300 hydraulic crawler water well drilling rig is mainly used for drilling water well and holes for water exploration. Also, it is used in creating small diameter holes for foundation construction and other engineering projects.

Features
1. This crawler water well drilling rig has two power heads and requires no drive rod. It has long feed travel which is helpful to reduce the reverse frequency of the drill rod, avoid block and improve efficiency. It can also achieve pressure-increasing and pressure-decreasing type drilling at full feed stroke conditions.
2. The front and rear power heads allow the drilling equipment to achieve a variety of drilling methods.
2.1 When drilling a hole in fractured zone and other troublesome zones, the drilling rig can be used to achieve percussion rotary drilling by connecting the drill rod power head with DTH hammer and bits. Meanwhile, the other power head drives the casing tube to rotate and thus protect the hole wall. The two power heads can work synchronously to crate holes rapidly.
2.2 While drilling a hole in ravelly ground, quicksand layer and silt layer, the water well drilling rig can achieve different types of drilling by using drilling tools like conventional rotary drilling tool and long anger drilling tool. Meanwhile, the front power head drives the casing pipe to rotate for hole wall protection.
2.3 While drilling a hole in intact formation, the drilling equipment can use only one power head to achieve rotary drilling and rotary percussion drilling.
3. Floating mechanism in the main spindle of top drive power head protects drill rod screw thread. Casing tube can also used as screw machine to achieve mechanical mounting and dismounting of drilling tools.
4. The water well drilling rig's feeding structure could work with winch together to meet special technical demands and reduce the workload of operators and other workers.
5. Equipped with world famous brand hydraulic motor, pump and operating valves, and other key components from Chinese top ranked manufacturers, the drilling rig is provided with reliable and stable performance and long service life as well.
6. The equipment is applicable for various drilling methods such as follow-up casing drilling, auger drilling, percussion rotary drilling, double wall reverse circulation drilling, and more.
7. With complete functions and high efficiency, it can be used to deal with any kind of accidents.
